Identifying your House Specialty

A simple yet important marketing activity for a restaurant to do is identifying its house specialty. This is the dish that the restaurant management deems what they can cook and serve best. It is what sets it apart and what it gives to guests when they ask for something special. It is the dish that is used in photoshoots or food reviews. It is the restaurant's signature.

Simply put, when a restaurant is not able to identify its specialty, there is a high probability that the people running the place are confused as to the identity of the restaurant itself.

So just how do you set your house specialty? Ideally, it should be the reason you opened the restaurant or the concept or dish in mind as inspiration.
It could also be the best dish you can serve, what the restaurant is famous for.

I think for those restaurants who do not have one, one possible reason is that they have other good stuff in the menu which are not necessarily their specialty. However, your specialty can also be a group of dishes or a cuisine. But definitely, a single dish or ingredient would be the best items to set as your house specialty.

So what is your restaurant's specialty?
